DESCRIPTION
d.rast.leg shows a raster map along with its legend. It first clears the entire screen, then divides it into a main (left) and a minor (right) frames, and displays a raster map in the main frame and the map legend in the minor frame. The main frame remains active when the program finishes.
NOTES
The legend may be flipped with the -f flag.
If the lines parameter is not given then the legend frame will display as many lines as number of categories in the map, otherwise, it will display the first lines minus 1 categories with the rest being truncated.
The user may adjust the lines parameter or the size of graphics window to get an appropriate result.
The user may specify a second raster map with the raster parameter from which the legend is generated. This is useful to visualize (time) series of raster maps with a common static legend instead of the default dynamic legend.
To remove all frames when clearing the display, use d.erase -f
.
EXAMPLE
In this example, the polar diagram of the 'aspect' angle map in the North Carolina sample dataset is generated:
g.region raster=landclass96 -p
d.rast.leg landclass96
